A demultiplexer for digital media files, or media demultiplexer, also called a file splitter by laymen or consumer software providers, is software that demultiplexes individual elementary streams of a media file, e.g., audio, video, or subtitles and sends them to their respective decoders for actual decoding. [1]
The process can then be reversed by the demultiplexer and 4 data streams produced with exactly the same bit rate as previously. The timing irregularity is ironed out using a phase locked loop. This scheme does not allow the addition of a stuffed bit as soon as it is required, because the stuffable bit is in a fixed point in the frame.
A device that performs the multiplexing is called a multiplexer (MUX), and a device that performs the reverse process is called a demultiplexer (DEMUX or DMX). Inverse multiplexing (IMUX) has the opposite aim as multiplexing, namely to break one data stream into several streams, transfer them simultaneously over several communication channels ...
Schematic of a 1-to-2 demultiplexer. Like a multiplexer, it can be equated to a controlled switch. In electronics , a multiplexer (or mux ; spelled sometimes as multiplexor ), also known as a data selector , is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. [ 1 ]
For example, when used as an address decoder, the 74154 [3] provides four address inputs and sixteen (i.e., 2 4) device selector outputs. An address decoder is a particular use of a binary decoder circuit known as a "demultiplexer" or "demux" (the 74154 is commonly called a "4-to-16 demultiplexer"), which has many other uses besides address ...
Demultiplexer An event notifier that can efficiently monitor the status of a handle, then notify other subsystems of a relevant status change (typically an IO handle becoming "ready to read"). Traditionally this role was filled by the select() system call, but more contemporary examples include epoll, kqueue, and IOCP. Dispatcher

For example, the downstream signal might be at 1310 nm while the upstream signal is at 1550 nm. [ citation needed ] The 10GBASE-LX4 10 Gbit/s physical layer standard is an example of a CWDM system in which four wavelengths near 1310 nm, each carrying a 3.125 Gbit/s data stream, are used to carry 10 Gbit/s of aggregate data.
